Catch this: 49ers wide receivers have 15(!) receptions

Yes, that’s what those guys – Michael Crabtree, Mario Manningham and Randy Moss – are called who accounted for 15 catches and 152 yards in the Niners’ 30-22 win at Green Bay on Sunday.

Those are relatively modest numbers (Packers WRs: 23 catches, 256 yards, TD), but they count as semi-historic for San Francisco. Fifteen catches? That’s 14 more than San Francisco’s wideouts had in the NFC Championship Game and it’s the most they’ve had in a game since 2010. Niners wide receivers hadn’t accounted for 15 catches in their previous 29 games (including playoffs), a streak during which wideouts averaged 7.9 catches and never had more than 12 catches in a contest.

The lack of field-stretching threats, of course, has contributed to the 49ers’ mostly miserable offensive performance over the past nine seasons. San Francisco, which hasn’t ranked higher than 23rd in total offense since 2003, is also one of two teams (the Bears) without a 1,000-yard wide receiver over that span.

On Sunday, speedy new additions Moss and Manningham combined for 8 catches, 76 yards and a touchdown, but their full impact is difficult to calculate.

Remember seeing Vernon Davis running free alone down the middle on his 29-yard, third-quarter catch? Moss was on the field, lined up on the opposite side of Davis, and ran a deep post to help create the wide open space in the middle of the field.

** The last time 49ers wide receivers had more than 15 catches was in a 27-24 loss to the Eagles on Oct. 10, 2010, when they had 16. The catches: Michael Crabtree (9), Josh Morgan (3), Ted Ginn (2), Dominique Zeigler (2).
